Part name
Inverter
assembly
Procedure Remarks
1) Perform work of item 1 in
.
2) Remove screw (ST1TØ4 × 10L 2 pcs.) of the
upper part of the front cabinet.
• If removing the inverter cover in this
condition, P.C. board can be checked.
• If there is no space above the unit, perform
work of 1 in
.
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
3) Perform discharging by connecting
,
polarity by discharging resistance (approx.
100
Ω
40W) or plug of soldering iron to
,
terminals a of the C14 (printed “CAUTION
HIGH VOLTAGE” is attached.) electrolytic
capacitor (760µF or 500
µ
F) on P.C. board.
Be careful to discharge the capacitor
because the electrolytic capacitor
cannot naturally discharge and voltage
remains according to trouble type in
some cases.
NOTE
This capacitor is one with mass capacity.
Therefore, it is dangerous that a large
spark generates if short-circuiting
between
,
Requirement
As each connector has a lock mecha-
nism, avoid to remove the connector by
holding the lead wire, but by holding the
connector.
Discharging position
(Discharging period
10 seconds or more)
Plug of
soldering
iron
The connector is one
with lock, so remove
it while pushing the
part indicated by an
arrow.
Be sure to remove the connector by
holding the connector, not by pulling
the lead wire.
4) Remove screw (ST1T
∅
4 x 10L 4pcs.) fixing
the terminal part of inverter box to the main
body.
5) Remove the front cabinet by performing step
1 in , and remove the fixing screws
(ST1T
∅
4 x 10L) for securing the main body
and inverter box.
6) Remove various lead wires from the holder
at upper part of the inverter box.
7) Pull the inverter box upward.
8) Disconnect connectors of various lead wires.
